Memory
Calculating Separate Totals
You want to tally yesterday’s sales (£450, £75, £145, and
£47) and still be able to calculate customer purchases.
You are interrupted by a customer who purchases items
for £85 and £57.
Part 1: Begin Sales Tally Using Memory

Multiplication with Memory Keys
You have £100.00. Can you purchase 3 items at £10.50, 7
items at £7.25, and 5 items at £4.95?
Using the memory keys does not disturb any current
calculation and also saves keystrokes.
